Drive device for inductive electrical actuators

Abstract

A control device (41) for inductive electrical actuators, comprising a power circuit (42) provided with a control circuit (11) couple each electrical actuator (12); comprising the said control circuit (11) switching means (27, 28, 29) controlled selectively to regulate the current flowing through the said electrical actuator (12); said control device (41) a control circuit (43) comprising for operating the power circuit (42); comprising the said control circuit (43): - a set of control modules (44), one for each control circuit (11), each of said control modules (44) which operate selectively said means switching (27, 28, 29) of a corresponding control circuit (11), and supplying a status signal (SFLAG) indicating the operating state of said control module (44) at its output; said control device (41) being characterized in that said control circuit (43) further comprises: - synchronization means (45) for receiving and processing the state signals (SFLAG), to generate a common timing signal (SSINC ) for synchronizing said control modules (44) each other; wherein said control module (44) is able to synchronize and coordinate, in accordance with said synchronization signal SSINC, operating actions sent to the switching means corresponding (27, 28, 29) with the operating actions sent by other control modules (44) to the corresponding switching means (27, 28, 29).
